Which ordered pair is the best estimate for the solution of the

Mathematics
1 answer:
natulia [17]2 years ago
8 0

Answer:

  (a)  (3.5, 1.6)

Step-by-step explanation:

The solution of the system of equations is the point where the lines cross. That point appears to be slightly above the middle of the grid square bounded horizontally by x=3 and x=4, and bounded vertically by y=1 and y=2.

__

The solution ordered pair is (x-coordinate, y-coordinate). We observe that the x-coordinate is approximately 3.5, The y-coordinate is slightly more than 1.5, but not as great as 1.9. So, the approximate solution is ...

  (x, y) ≈ (3.5, 1.6)

_____

The graphing calculator shows the solution is quite close to (3.5, 1.6).

Round 18.049 to the nearest tenth.
kirill115 [55]

Answer:

18.0

Step-by-step explanation:

Note the tenth place value (underlined and bolded): 18.<u>0</u>49

Look at the number to the direct right of the tenth place value (or the hundredth place value in this case). It is a 4.

Note the rules of rounding. If the number:

1) is 5 or greater, round up.

2) is 4 or less, round down.

In this case, it is 4, so you will round down.

18.049 rounded to the nearest tenth is 18.0

A plane traveled 2565 miles with the wind in 4.5 hours and 2205 miles against the wind in the same amount of time. Find the spee
kherson [118]

Answer:

  • plane: 530 mi/h
  • wind: 40 mi/h

Step-by-step explanation:

Let p and w represent the speeds of the plane and the wind. The relation between time, speed, and distance is ...

  speed = distance/time

  p +w = (2565 mi)/(4.5 h) = 570 mi/h

  p -w = (2205 mi)/(4.5 h) = 490 mi/h

Adding these speeds, we get ...

  (p +w) +(p -w) = (570) +(490) mi/h

  2p = 1060 mi/h

  p = 530 mi/h

Then the speed of the wind is ...

  w = 570 mi/h -p = (570 -530) mi/h = 40 mi/h

The plane's speed is 530 mi/h; the wind speed is 40 mi/h.

Strike441 [17]

Answer:

  • y + 2 = 5x

Step-by-step explanation:

<u>Point-slope form: </u>

  • <em>y - y1 = m(x - x1)</em>

<u>Slope formula:</u>

  • <em>m = (y2 - y1)/(x2 - x1)</em>

<u>Given points:</u>

  • (0, -2) and (3, 13)

<u>Finding the slope:</u>

  • m = (13 - (-2))/(3 - 0)
  • m = 15/3
  • m = 5

<u>Using point 1</u>

  • y - (-2) = 5(x - 0)
  • y + 2 = 5x
